    Interesting. I'll experiment with my Plone 3.3.4 ZEO cluster on a G4 PowerPC Xserve, where physical RAM is limited to 2 GB …

  • Plone 4 is faster out of the box than some of the most common PHP platforms

  • Jon Stahl
  • Plone 4 is about to
  • enter beta testing prior to a final release
  • performance
  • out of the box
  • over three times faster
  • what does all this mean?  Well, honestly, not much
  • realistic sample content
  • very, very proud of Plone’s raw speed
  • suspect MAMP not to be very efficient
  • For read-only operations, once the objects have made it into ZODB’s object cache no database queries need be made
  • the difference is down to Plone’s use of the ZODB
  • Contrast this to the PHP/MySQL systems which must perform several selects in order to render the page
  • to fetch new objects it’s slower
  • ZODB fetches are serial
  • Archetypes persistent object design is far from optimal (page data is split over several persistent objects, slowing down load time)
  • addressed as part of Dexterity
  • fundamental architectural difference
  • CMSes that use the RDBMS and some kind of ORM or manual SQL (like Drupal, Joomla)
  • those that use an OODBMS such as Plone
  • ‘out of the box’ speed, since that is something a lot of people historically have not liked about Plone
  • less tuning needed to start with
  • even when caching is not applicable we still get the performance boost
  • our installer sets up ZEO with clients for you, so this is “out-of-the-box”
  • counter the (incorrect) perception out there that “Plone is slow”
